  • In this video from AMETEK Precision Moton Control, engineer Patrick Melick — of the Dynamic Fluid Solutions Group — explains how to install a blower in a spa. Patrick shows a typical installation with components, starting with the airline to the spa. (Shown in this video is a setup that uses a ROTRON Regenerative Blower.) Here are some tips explained in more detail in the video:

    The airline should be at least two inches in diameter … or if it’s more than 50 feet long, it should be three inches in diameter.

    As with all plumbing, keep bends to a minimum! However, include a Hartford loop that’s at least 12 inches above the blower. That will protect the electrical component from getting flooded with water.
    Install a low-pressure check valve at the output.

    Put a muffler on the output flange to make the spa or hottub bubbler quieter. Also use metal pipe (with the geometry and length as Patrick explains) with a pressure-relief valve and a gage.
    Mount the blower to the floor and wire it according to the directions on the blower’s barrel.

    Make sure that the blower is moving in the right direction by covering the outlet with a stick or large piece of cardboard, and feel for air movement. “Due to different phasing across the country, air may be coming out of what’s normally the inlet side,” says Melick. Switch wires 5 and 8 to solve the problem … easy.

    With a few final steps to bolt the blower to the circuit, you’re ready to add bubbles to your spa!

    AMETEK ROTRON® line of regenerative blowers are designed based on the regenerative principle. The impeller blades passing the inlet port of the blower draw air or other gasses into the blower. The impeller blades then, by centrifugal action, accelerate the air outward and forward. Here the “regenerative” principle takes effect as the air is turned back by the annular shaped housing to the base of the following blades where it is again hurled outward. Each “regeneration” imparts more pressure to the air. When the air reaches the stripper section at the outlet (the stripper is the part of the blower located between the inlet and the outlet in which the annulus is reduced in size to fit closely to the sides and tips of the impeller blades) the air is “stripped” from the impeller and diverted out of the blower. The pressures or vacuums generated by the one or two spinning, non-contacting, oil-free impellers are equal to those obtained by many larger multi-stage or positive displacement blowers.

    Regenerative blowers are available in many configurations designed to meet specific applications.



    A simple guide to controlling 12 volt LED strips from your Arduino using an N Channel Mosfet.

    In my example I’m using PWM to fade the 12v LED strip, but you could just as easily turn the LED strip on and off instead of fading it. Also it doesn’t have to be an LED strip and it doesn’t have to be 12v!

    If you’re going to drive a motor or a relay (or any inductive load) using this setup, you should add a diode across the positive and negative input of the motor/relay to avoid any back voltage.

    I’ve over simplified things in terms of my description and the circuit, but it should be enough to get you up and running and to give you a basic understanding of how an N-Channel Mosfet works.

    Pretty much any N Channel Mosfet will be fine, but ideally you want to go for an L series, because the gate can be reliably driven at lower voltages, such as the 5 volt from the Arduino.

    If you’re curious, a MOSFET is a metal–oxide–semiconductor field-effect transistor. The benefit of a MOSFET over the traditional relay is that it can turn on and off extremely quickly, meaning it’s suitable for PWM, compared to the old coil relay which can’t turn on and off so quickly. Of course a modern solid state relay can compare against a mosfet or transistor.
